Solar Panel Wiring
can i charge the 12v battery directly by Solar Panel?
i have 2 batteries of 12v, 100amp. can i charge them by the solar panel directly plugging the wire without any equipment.
if i, how many or square feet solar panel i required and what the cost of it.
I assume you mean 100 amp-hour batteries, not something that says “100 cranking amps”.
For 200 AH of batteries at 12V, you would want about a 100W panel or larger. You would probably want a charge controller, because the currents involved would be on the order of 10 A max, possibly damaging to the batteries after they are fully charged.
A panel of that size is about $300-$400.
